Nature reserves are not only for bird watchers and walkers but may also be visited by school parties for whom toilet facilities are essential. Very busy reserves might benefit from a new toilet system we designed for Richmond Park instead of the twin vault composters shown below.
Some examples of NatSol toilets on nature reserves:-

Hilbre is a Local Nature Reserve within a Site of Special Scientific Interest, a Special Protection Area, a Wetland of International Importance, a candidate Special Area of Conservation and a Regionally Important Geological and Geomorphological Site.
Our waterless toilets were chosen mainly because of their low environmental impact.
